Multiple WoW account (do they share achievments under the same battle. net account? if so) with 1 person playing each account and leveling. Possibly different persons leveling professions as well. Fightning account sharing is not exactly Blizzards #1 prio.

Just imagine that somewhere in the world right now, an extremely fat, unattractive lonely man's life has been a tiny bit better with all those achievements. Satisfied and having spent an absolute fortune on this conquest, he dips his chocolate into a half-empty pot of peanut butter and gorges himself; his bare, flabby and grotesque body illuminated by the glow of his computer screen and somewhere amidst the heavy, fleshy folds upon his head that hide his face, a small and drool-glazed smile forms.

His life is complete, and those of us attached to the realm of reality know this; it is only a game.

If the computers are located on the same IP then Blizzard can't do anything about it. They can't prove that the person isn't playing all the computers himself.

Nor they care. I mean it's not even slightly suspicious that players who have never played arena before suddendly move to different IP in different country, reach gladiator range, and never play again.
